Use exclamation points effectively. I’m a fan of the exclamation point. I use them all the time in Facebook posts or text messages when I want to note my exuberance about something, which is quite often. But posts and texts are quick and solitary bursts of information:
Finished my taxes! Yippee!
It’s GAWGEOUS outside!
When it comes to writing a novel, I use them much more sparingly. You have to, or else the overuse — just like with adjectives or adverbs — will minimize their effectiveness. I read recently that you should have no more than two or three exclamation points per 100,000 words of prose. Since I’m a thriller writer, I suspected I had way more than that ratio in Baby Grand, and a quick “find” proved me right — by page 44, I’d already counted nine.
But that’s okay. In my opinion, the number of times you use exclamation points is not really the point; it’s whether or not you are using them efficiently and successfully. And if you are, then yippee!
